What does FLEX measure?
Mean Velocity shows the mean speed of the bar across the concentric phase of every rep. Use this metric to maintain intensity throughout your set, choose the right weight for that day and track progress over time.
Peak Velocity shows the maximal bar speed during a lift. This metric is typically used for Olympic lifts and ballistic movements. Peak Velocity offers immediate feedback on how fast you're actually moving, not how fast you think you are.
Mean Power is a measure of strength (ability to produce force) and speed across the concentric phase of your lift. Use power to get feedback on lift performance and track progress over time.
Peak Power is the highest power output achieved in a lift. As expected, the metric is useful for Power and Olympic lifts but is just as applicable to other explosive movements.
Distance measures the vertical displacement of the bar from the lowest point of your lift to the highest. Use Distance to maintain range as you fatigue and guide technique improvements - eg. is your squat shortening up as the load increases?
Height measures the vertical displacement of the bar, adjusted for any dip in the movement. This is particularly useful for jump testing where the measure adjusts for the dip prior to the explosive movement.
Efficiency and safety. Bar Path displays the horizontal displacement of the bar away from your start position. Minimising horizontal movement improves efficiency and safety in most vertical lifts.
Bar Movement tracks vertical displacement of the bar to graphically represent the concentric and eccentric phases of your lift. Use Bar Movement to improve technique and efficiency by working through flat spots or smoothing out jerkiness. This is a line graph showing you the 2-dimensional output of the movement.
